5 | ## Example
|
6 |
|
7 | ```js
|
8 | // x ** y
|
9 |
|
10 | let squared = 2 ** 2;
|
11 | // same as: 2 * 2
|
12 |
|
13 | let cubed = 2 ** 3;
|
14 | // same as: 2 * 2 * 2
|
15 |
|
16 |
|
17 | // x **= y
|
18 |
|
19 | let a = 2;
|
20 | a **= 2;
|
21 | // same as: a = a * a;
|
22 |
|
23 | let b = 3;
|
24 | b **= 3;
|
25 | // same as: b = b * b * b;
|
26 | ```
